1. Create an application at the OAuth provider site.
2. Use these credentials for registration of an OAuth client in your project.
For example, Facebook:
C#
OAuthManager.RegisterClient
(
"facebook",
"1435890426686808",
"c6057dfae399beee9e8dc46a4182e8fd"
);Visual Basic .NET
OAuthManager.RegisterClient _
(
"facebook",
"1435890426686808",
"c6057dfae399beee9e8dc46a4182e8fd"
)3. Create a page to handle the callback. And add code to obtain user data with external server.
For example:
C#
public partial class ExternalLoginResult : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
var result = OAuthWeb.VerifyAuthorization();
Response.Write(String.Format("Provider: {0}<br />", result.ProviderName));
if (result.IsSuccessfully)
{
var user = result.UserInfo;
Response.Write(String.Format("User ID: {0}<br />", user.UserId));
Response.Write(String.Format("Name: {0}<br />", user.DisplayName));
Response.Write(String.Format("Email: {0}", user.Email));
}
else
{
Response.Write(result.ErrorInfo.Message);
}
}
}Visual Basic .NET
Public Class ExternalLoginResult
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim result As AuthorizationResult = OAuthWeb.VerifyAuthorization()
Response.Write(String.Format("Provider: {0}<br />", result.ProviderName))
If result.IsSuccessfully Then
Dim user As UserInfo = result.UserInfo
Response.Write(String.Format("User ID: {0}<br />", user.UserId))
Response.Write(String.Format("Name: {0}<br />", user.DisplayName))
Response.Write(String.Format("Email: {0}", user.Email))
Else
Response.Write(result.ErrorInfo.ToString())
End If
End Sub
End Class4. Get the address for authentication and redirect the user to it.
C#
string returnUrl = new Uri(Request.Url, "ExternalLoginResult.aspx").AbsoluteUri;
OAuthWeb.RedirectToAuthorization("facebook", returnUrl);Visual Basic .NET
Dim returnUrl As String = New Uri(Request.Url, "ExternalLoginResult.aspx").AbsoluteUri
OAuthWeb.RedirectToAuthorization("facebook", returnUrl)5. Enjoy!
